  2. 7.2 Similar Polygons

  3. Similarity F G ABCD ~ EFGH B C 5in 3in 72° E H D A 6in Similar Polygons: Polygons having corresponding angles congruent and corresponding sides proportional (denoted “~”). Similarity Ratio: The ratio of the lengths of corresponding sides in similar polygons.

  4. Similarity Given LONM ~ QTSR below, find the value of x.

  5. Similarity Determine whether the triangles are similar. If they are, write a similarity statement and give the similarity ratio. E B 78° 20 16 15 12 78° 35° 67° D F A C 24 18

  6. Golden Ratio GOLDEN RECTANGLE ACTIVITY!!!!

  7. Golden Ratio Golden Rectangle: A rectangle that can be divided into a square and a rectangle that is similar to the original rectangle. The Golden Ratio is ≈ 1.618 An artist plans to paint a picture. He wants the canvas to be a golden rectangle with its longer horizontal sides 30cm wide. How high should the canvas be?
